Description
- This application claims priority to U.S. Provisional Patent Application Ser. No. 62/940,065, filed Nov. 25, 2019, which is hereby incorporated by reference herein.
- Embodiments disclosed herein relate to a towing hitch that mounts securely onto a receiver hitch of a towing vehicle, and adjusts and/or folds to provide clearance behind the towing vehicle. In particular, towing hitches that are designed for use with step-equipped tailgates but can be used on most vehicles having conventional receiver hitches.
- Towing hitches are devices used to attach a trailer to a towing vehicle. The most common type of hitch for recreation and/or work vehicles is the bumper pull. On this type of hitch, a tongue of a trailer is attached to a receiver hitch that is accessible from a rear end of the towing vehicle. The towing hitch is commonly inserted into the receiver hitch that is attached to a frame of the towing vehicle.
- There are several common problems with this style of towing hitch. The first problem is hitch height. The towing hitch may need to be at several heights to accommodate various vehicle receiver hitch heights as well as various trailer tongue heights. A second problem is that towing hitches can move around or rattle in the receiver hitch. A third problem is that an installed towing hitch protrudes from the rear end of the towing vehicle which may create safety issues as well as other problems. For example, the protruding hitch is an obstacle and may cause parking issues, such as when parking in garages and/or near other vehicles. The protruding hitch could also cause clearance issues with step-equipped tailgates on some vehicles. These step-equipped tailgates require that the towing hitch be removed from the towing vehicle before utilizing some functions of the step-equipped tailgate.
- What is needed is a towing hitch that alleviates one or more of the problems discussed above.
- Embodiments of the disclosure include a towing hitch that includes one or more features that allow use thereof with a step-equipped tailgate. In one embodiment, the towing hitch includes a mounting plate that has a profile that is recessed from conventional hitches thus providing a critical clearance enabling utilization of a step-equipped tailgate without removing the towing hitch from the vehicle.
- In another embodiment, a towing hitch is disclosed that includes a mounting plate coupled to a tubular insert that is couplable to a tubular receiver member on a towing vehicle having a step-equipped tailgate, and a hitch plate coupled to the mounting plate by a hinge mechanism, the hitch plate adapted to secure a trailer ball, wherein the hinge mechanism is coupled to the mounting plate by a pivot pin that allows rotation of the hitch plate relative to the mounting plate to a stowed position such that a critical clearance between the step-equipped tailgate and the mounting plate is provided.
- In another embodiment, a towing hitch is disclosed that includes a mounting plate coupled to a tubular insert that is couplable to a tubular receiver member on a towing vehicle having a step-equipped tailgate, and a hitch plate coupled to the mounting plate by a hinge mechanism, the hitch plate adapted to secure a trailer ball, wherein the hinge mechanism is coupled to the mounting plate by a pivot pin and one or more stabilizing pins, wherein by removing the one or more stabilizing pins rotation of the hitch plate relative to the mounting plate is provided such that utilization of the step-equipped tailgate is enabled without removing the tubular insert from the towing vehicle.
- In another embodiment, a towing hitch is disclosed that includes a mounting plate coupled to a tubular insert that is couplable to a tubular receiver member on a towing vehicle having a step-equipped tailgate, and a hitch plate coupled to the mounting plate by a hinge mechanism, the hitch plate adapted to secure a trailer ball, wherein the hinge mechanism is coupled to the mounting plate by a pivot pin that allows rotation of the hitch plate relative to the mounting plate to a stowed position such that utilization of the step-equipped tailgate is enabled without removing the tubular insert from the towing vehicle.

FIG. 1 shows atowing vehicle 100 having a step-equippedtailgate 105. The step-equippedtailgate 105 includes aprimary gate 110 with aninternal gate device 115. Theinternal gate device 115 includes a first hingedpanel 120 and a second hingedpanel 125. Theprimary gate 110 is shown as being open and moves to a closed position in the direction ofarrow 130. The first hingedpanel 120 is shown as being open and moves to a closed position in the direction ofarrow 135. The second hingedpanel 125 is shown as being open and moves to a closed position toward the first hingedpanel 120 in the direction ofarrow 140. In the open position, the second hingedpanel 125 functions as astep 145. - The
towing vehicle 100 also includes areceiver hitch 150 that is adapted to receive a towing hitch (not shown inFIG. 1 ). In this configuration, the towing hitch is removed from thereceiver hitch 150 in order to accommodate the step-equippedtailgate 105 in the open position. For example, a critical clearance (e.g., a protrusion or protruded distance) 155 is present when the step-equippedtailgate 105 is in the open position as shown. If a towing hitch was installed in thereceiver hitch 150 when using the step-equippedtailgate 105 as shown, the towing hitch would damage the step-equippedtailgate 105 and/or prevent proper operation of the step-equippedtailgate 105. As such, a user must remove the towing hitch to enjoy full use of the step-equippedtailgate 105. In most cases, thecritical clearance 155 is less than 1 inch (measured between a surface of the first hingedpanel 120 facing thetowing vehicle 100 and the receiver hitch 150). Thiscritical clearance 155 is too small for conventional towing hitches to remain coupled to thereceiver hitch 150 when using the step-equippedtailgate 105 as shown inFIG. 1 . -
FIGS. 2-6 are various views of an embodiment of astowable towing hitch 200 according to embodiments disclosed herein.FIG. 2 is a sectional view of thereceiver hitch 150 having thestowable towing hitch 200 installed therein.FIG. 3 is an isometric view of the mountingplate 225.FIGS. 4 and 5 are a side view and an isometric view, respectively, of thereceiver hitch 150 having thestowable towing hitch 200 installed therein.FIG. 6 shows one embodiment of thestowable towing hitch 200 in a stowed position. - The
receiver hitch 150 includes atubular receiver member 205 that is typically rectangular metal tubing. Thetubular receiver member 205 typically has an end that extends or protrudes past a rear of the towing vehicle 100 (shown inFIG. 1 ). Thestowable towing hitch 200 includes a tubular hitch member 210 (e.g., a tubular insert portion) that is inserted into avolume 215 of thetubular receiver member 205. Similar to thetubular receiver member 205, thetubular hitch member 210 is typically rectangular metal tubing that is sized slightly smaller than an inside dimension of thetubular receiver member 205. A through-hole 220 is provided in both of thetubular receiver member 205 and thetubular hitch member 210. The through-holes 220 are sized to receive a pin (not shown) that secures thestowable towing hitch 200 to thereceiver hitch 150 when the through-holes 220 in both of thetubular receiver member 205 and thetubular hitch member 210 are aligned. - The
stowable towing hitch 200 includes a mountingplate 225 that is fixed or fastened to thetubular hitch member 210. The mountingplate 225 supports ahinge mechanism 228. Ahitch plate 230 having a through-hole 235 where a trailer ball 240 (two are shown) is fastened to thehinge mechanism 228. Thehinge mechanism 228 includes two L shapedbrackets 232. Thehitch plate 230 is fastened to one leg of the L shapedbrackets 232 such as by a weld (not shown). The mountingplate 225 is sandwiched between the other leg of the L shapedbrackets 232. - Referring to
FIGS. 2, 4 and 5 , the mountingplate 225 includes a plurality ofopenings 255 formed therethrough in a direction parallel to the through-holes 220 (e.g., in a “cross-machine” direction). Thehinge mechanism 228 also includes one or more through-holes 234 that align with theopenings 255 formed in the mountingplate 225. Thehinge mechanism 228 includes apivot pin 245 disposed in one of theopenings 255 of the mounting plate 225 (and the through-holes 234 of the hinge mechanism 228). Thepivot pin 245 allows the hinge mechanism 228 (including thehitch plate 230 and the trailer ball 240) to pivot relative to the mountingplate 225 in the direction ofarrow 250. Thus, in the position shown inFIG. 2 , one or more stabilizing pins 400 (shown inFIGS. 4 and 5 ) may be inserted intoother openings 255 formed in the mountingplate 225 adjacent to theopening 255 where thepivot pin 245 is located, and thestowable towing hitch 200 may be used for towing a trailer. However, when the one or more stabilizingpins 400 are removed, thehinge mechanism 228 allows thestowable towing hitch 200 to pivot out of the way such that the step-equippedtailgate 105 may be opened as shown inFIG. 6 . Each of thepivot pin 245 and the one or more stabilizingpins 400 are secured to the mountingplate 225 by aretainer 405, such as a cotter pin. - Referring again to
